water plant Flowrate is 0.044 m3 /s and alum is used to remove particulate matter, reducing the concentration of organic matter and reduce the alkalinity of water according to the following equation: Al2(SO4)3.14H2O + 6HCO3 - 2Al(OH)3 (s) +6CO2 + 14H2O + 3SO2- 4 If the organic matter concentration is reduced from 8 mg/L to 3 mg/L, determine the total mass of alkalinity consumed and the total mass of dry solids removed per day using the optimum dosage obtained.
